HENRY KIELBERG, or MARTINS FERRY, 01110, AssIGNoR 'ro WHITAKER-GLESSNERCOMPANY, or WH ELING, WEST VIRGINIA, A CORPORATION or WEST VIRGINIA;

GRID EoR GAS AND OIL STOVES.

Application filed October 5, 1921.

1 '0 all whom it may concern I Be it known that I, HENRY KIELBERG, acitizen of the United States of America, and resident of Martins Ferry,county of Belmont, and State of Ohio, have invented certain new anduseful Improvements in Grids for Gas and Oil Stoves, of which thefollowing is a specification.

This invention relates to stove grids vof the general character commonlyemployed for seating within the usual circular holes of stove tops, andit has for its primary object to provide a grid constructed of asheetmetal stamping pressed or drawn into a novel form which affords therequisite rigidity and strength and which is adapted to successfullyresist the usual tendency to become warped from heat. I

A further object is to which, in addition to being strong'and durable,is light in weight and is comparatively inexpensive to manufacture.

In describing the invention in detail, reference is herein had to theaccompanying drawings, in which- Figure 1 is a top plan view of theinvention, and- Figure 22, Fig. 1.

The grid constituting the inventionis fabricated from a circularsheet-metal plate or stamping and comprises a plurality of con centricupwardly pressed beads, as 2 and 3, each substantially semi-cylindricalin cross section, connected by relatively spaced radial ribs 4:, alsoupwardly pressed into approximately semi-cylindrical I'orm,'said ribsbeing separated by openings or perforations 5. A central opening 6 isencircled by the provide 1 a grid 2 is a section of the same on lineSerial No. 505,458;

- inner bead 3 which may have shoot tongues 7 projecting1 radiallyinward therefrom. En-

circling flange or rim 1 for resting'upon the usual seating ledge whichsurrounds the top hole of a stove. I

The convex top surface of the beads 2 and 3, the ribs 4 and the tongues7 are disposed in a common horizontal plane, asshown in Fig. 2.

As is apparent, the grid described may be readily produced by simple andcommon pressing or drawing methods, and, conse quently, isirelativelyinexpensive to manufacture. Moreover, the concavo-convex form of thevarious parts of the structure provides not only for strength andrigidity, for great resistance against warping.

What is claimed is- Y As a new article of manufacture, a onepiecefretwork grid for the circular holes of stove tops, said grid. beingstamped from sheet metal and consistin of concentrically disposed rings,relative y spaced radial bridges joining said rings, said rings and saidbridges being pressed into substantially semi-cylindrical form in crosssection, the spaces between said rings and said bridges being whollyopen'to thepassage of flame,

and a circular seating flange extending outa wardly from the outer ofsaid rings.

In testimony whereof, I aflix my signae outer bead 2 is a flatterminalg5-5 but alsol.
